Batman '66 #16

It’s “Egghead Unbound” as Batman’s most egg-centric foe returns to terrorize Gotham City. Frustrated by his repeated defeats at the hands of the Caped Crusader, he invents a device that will egg-celerate his brain development to that of a being from the 40th century. Is this really possible? Does he now possess super-human abilities? Or has his mind simply gotten scrambled?

Characters: Batman, Catwoman, Chief O'Hara, Dick Grayson, Egghead (Edgar Heed), Eggna, Mr. Freeze, Riddler
